The past week has seen quite a few changes in the zen domain. Change, they say, is a necessary evil, so rather than dwell on what was we now look forward to what it would now be.

Zen-sources, as it was called, has a new name and a new home. It is now called zen-kernel and the new home can be found at http://zen-kernel.org/. Tutorials on how to install zen-kernel for the Linux distro of your choice are already up and this is where you should be headed. Because zen-kernel is still the way Linux Kernels should be. I would be posting benchmarks results of vanilla kernel vs. the Zen kernel pretty soon. Details will follow later, but right now I am not in favour of using phoronix test suite. I would rather benchmark more day-to-day tasks and see how the respective kernels perform.

Back to the changes in the zen land for now. The zen developers are also looking for a new logo. There is already a lively discussion in place at the Gentoo forums. Head over there, in case you want to take a sneak peek at the submissions that have been made so far.

And now the biggest change so far. This one is certainly for the positive. Zen kernel is now in portage (a big yay for all Gentoo users – it is now even easier to get zen). So, fellow Gentoo users, what are you waiting for? emerge zen-sources awaits you.

Zen-Sources is a collaborative effort of kernel hackers and enthusiasts to provide the best Linux kernel possible. We include code that is not yet found in the mainline kernel in an attempt to support the latest hardware, new features, security fixes, optimizations, etc.

Now, on to the important stuff:

Installation Guide for Gentoo Linux. (here). I recommend following the hand based git setup. (here).

For other distros, see the git mentioned in 1. (or check the repos and forums forums for your distro)

As you might have guessed from my recommendation, I have been using the git based setup on my Gentoo Linux install as my primary kernel. It has worked for me most of the time (there have been instances where the use of a kernel in rc stages has induced a bug or two – but this has seldom been the case and there is always the possibility to switch back to the stable release of zen sources).

There is a long list of projects that are included in zen sources (see the full list here) but the major advantages that I would think worth mentioning are:

Zen Tune

Brain Fuck Scheduler (don’t judge on the name)

BFQ

No problem with suspend/hibernate (and this is without TuxOnIce)

I would definitely suggest everyone to have a go at this. You will like it.
